Originally started as a Matrix mod, Existence has grown to be one of the greatest, also one of the most underrated, mods to be released for Half-Life! Feature abilities such as high jumps, long jumps, and speed boosts, a large arsenal for both teams, and of course lots of phone teleportation! ;) Give it a chance, you know you wanna, and you should! Since then we've moved to HL2. Everything you see on this page is from the HL version, but sit tight. The new stuff is coming!
